Abstract:
Methods and systems for making ammonia are provided. The method can include heating a first compressed syngas to produce a heated first syngas. The heated first syngas and a second compressed syngas can be combined to produce a combined syngas. The combined syngas can be reacted within a first ammonia converter and a second ammonia converter to produce an ammonia product. Heat from the ammonia product can be transferred to a first heat transfer medium to produce a first cooled product and a second heat transfer medium. Heat from the first cooled product can be transferred to a third heat transfer medium to produce a second cooled product. Heat from the second cooled product can be transferred to the combined syngas to produce a third cooled product. The third cooled product can be separated to produce a purified ammonia product and a recycle gas.
